I've encountered this in several different projects and solved it with
similar techniques.
It would be useful if there was a way allow for both blocking (the
current default) and bubbling.
Once a user gets used to this behavior it's not terribly difficult to
utilize a parent.onfoo.sendEvent() pattern, but an alternate solution
may be cleaner.
